Application
An effective way to supply the high level potentiometers is to use our constant voltage source KSQ 10 V, which allows it to compensate for both small potentiometer inaccuracies, or full-scale deflections.
The low capacity potentiometer tap can then be given a greater capacity by connecting an interface module in series. The 0...10 V signal can be converted into another signal standard, using the AKT, which is also potential-free. It is also possible to digitize directly into 8 or 12 bits by using a Wieland ADW.
